No, it wouldn't get dull. Things don't get dull just because they've been around some time, that's what folk music people know better than anyone else.

What new songs do is to help us make sense of new things that are happening in our lives, and we need that. Singing goes back earlier than talking, I believe, both in our own personal existence and in the life of the human race.

New songs help take us forward, and they keep us in touch with where we've come from, if they're the kind of songs I'm thinking about.
